Steel Windows and Doors

On ArchiPro, you can compare steel doors and windows alongside the wider building product range, making it easier to plan structure, glazing, hardware and finishes together. For New Zealand projects, pay close attention to corrosion protection, thermal performance, wind zone requirements and the way each system connects with surrounding cladding and internal linings.

Steel frame windows and doors are often selected when design intent is as important as function. They can create a crisp industrial look, a refined heritage reference or a minimalist architectural opening. Crittall-style steel windows and doors are a popular search term for slim gridded glazing, though buyers should compare the actual product system, finish and performance rather than relying on style labels alone.

• Exterior openings: use steel-framed glazing where strong profiles, large glass areas or custom proportions are required.
• Entry areas: steel entry doors can give a front elevation a clear architectural focal point.
• Interior zoning: glazed steel interior doors and partitions divide spaces while keeping visual connection.
• Commercial projects: steel suits shopfronts, hospitality interiors and workplace meeting rooms where daily use is high.

Not all steel systems are the same. Hot rolled steel windows and doors have a particular profile shape and feel, while other fabricated systems may use different sections, coatings or joinery methods. For coastal, urban and high-exposure sites, ask suppliers about galvanising, powder coating, stainless components and maintenance requirements.

Glazing has a major effect on comfort, safety and energy performance. Review the full glass specification through glazing options, including double glazing, safety glass, acoustic glass, privacy glass and low-E coatings. For large panes, balustrade-adjacent panels or doors in busy areas, the glass type should be chosen with the supplier, designer and installer.

Steel openings need hardware that matches the weight, exposure and use of the door or window. Hinges, pivots, locks, stays, handles and seals should be specified as part of the system. Compare suitable window and door hardware early, especially for double steel doors with windows, tall pivot doors or multi-panel configurations.

If the project includes integrated joinery, sliding systems or mixed materials, explore joinery systems to understand how frames, thresholds and surrounding construction can be resolved. For window-specific product options, see windows.

The cost of steel windows and doors depends on size, profile type, glass selection, finish, hardware, access and installation complexity. Custom steel doors and windows usually cost more than standard aluminium systems, but they can deliver slimmer frames and a stronger architectural result. Curved heads, heritage bars, large panes, thermal breaks and special coatings can all affect pricing.

For accurate quotes, prepare drawings, opening sizes, site location, wind zone information, finish preferences and any acoustic or thermal targets. Ask whether the quote includes shop drawings, delivery, installation, flashings, hardware and final adjustment. This makes it easier to compare suppliers fairly.

Steel windows and doors rarely sit in isolation. External shading, insect protection, garage access and glass care can all affect the final result. Explore external louvres and shutters for solar control and privacy, or insect and fly screens for ventilation without pests. If the home includes vehicle access, compare garage doors in finishes that sit well with steel joinery.

For long-term appearance, consider glass protection and treatments, especially in coastal areas, high-traffic homes and commercial spaces. The best result comes from aligning the steel frame, glass, hardware, flashings and maintenance plan before orders are placed.

• Confirm the system suits the project location, exposure and New Zealand conditions.
• Ask about thermal performance, condensation control and double glazing compatibility.
• Check lead times for custom profiles, finishes and imported components.
• Review installation details with your architect, builder or supplier before fabrication.
• Compare warranties for frames, coatings, glass units and hardware separately.
